AP mode not working on Sony A7rv


Recommended Posts

Hello,

Seeking advice. The AP mode will not change the aperture. The dial is working fine. I have checked all settings and even did a factory reset. When I switch the dial to AP, the shutter speed change, the F stop remains fixed at 20. The ISO remains the same. The compensation +/- changes. Any ideas what is going wrong?

Thank you for the welcome. My apologies as I was not very clear in my post. I was referring to the A mode, Aperture priority mode. It does not let me adjust the aperture and stays locked on F20.

You can control which dial is used for which parameter. In M it defaults to a particular assignment of aperture and shutter (I think Aperture is front dial). In A I think the default is both dials control aperture (again, you can change this).

There have been times when I have thought a dial wasn’t working, but the answer was that I already had the lens wide open, so any attempt to open it further was ignored (I think the camera was screaming at me “go buy another lens if you want it wider than this!”). In my defence, I had forgotten that I had the 1.4x attached, and that makes it hard to open up wider than f/4 on the 70-200 f/2.8!

My strong recommendation is: when the dial appears not to be working, try turning it the opposite direction - this will tell you immediately if you’d reached the limit. It also lets you know if you’d switched the direction of the dials (yet another thing you can change).

Thank you for all of the advice. The dial is definitely set to A. If I move the wheel left or right the aperture remains fixed at f22. I have tried changing the iso and no change with aperture for either lens. The aperture does change in manual mode. It is frustrating me. I wonder if there is a setting in the menu that is blocking this?
